Orion Luminance/IR Cutoff Filter, 1.25"Designed for use with the StarShoot Deep Space CCD Monochrome Imager II and similar cameras, this filter efficiently blocks ultraviolet (UV) and infrared (IR) wavelengths, which can cause blurring and glare, color abnormalities, and reduced contrast in CCD images from cameras lacking a built-in UV/IR filter. The steep cutoffs below 390nm and above 690nm and the high (typically 97% or better) transmission of visual wavelengths -- including the important 656nm H-alpha line -- make this an excellent luminance ...Read MoreDetails on Orion Luminance/IR Cutoff Filter, 1.25"

Orion LRGB Imaging Filter SetTake your astro-imaging to the next level with this set of 1.25" Luminance (IR cutoff), Red, Green, and Blue filters. They're designed for creating high-quality composite color astrophotos with the Orion StarShoot Deep Space CCD Monochrome Imager II (#52083) or similar cameras. Combining separate images taken through these four filters with a monochrome CCD provides a higher-resolution final image than an image from a comparably sized color CCD. Our LRGB set features dichroic glass filters designed for maximum ...Read MoreDetails on Orion LRGB Imaging Filter Set

Orion V-Block Anti-Fringing Filter, 1.25With refractors, it's normal to see some purple fringing or halos around bright objects such as the planets, Moon, and bright stars. Such false color, or chromatic aberration, results from the inability of a standard two-element ("achromatic") lensRead MoreDetails on Orion V-Block Anti-Fringing Filter, 1.25

Orion SkyGlow Imaging Filter 1.25"Introducing a must-have filter for any astrophotographer that doesn't happen to live on Mauna Kea. With the SkyGlow Imaging filter you can take incredible deep-sky images under light-polluted skies with your CCD or DSLR camera. That's because we custom designed the filter to selectively block the specific wavelengths of light associated with urban sky glow, letting the light emitted from deep-sky objects shine through. You'll see a marked increase in image contrast for all types of deep sky objects, even faint ...Read MoreDetails on Orion SkyGlow Imaging Filter 1.25"

Orion Hydrogen-Beta Nebula Filter, 1.25"Our Hydrogen-Beta Filter may be the only way to see the faint and elusive Horsehead, California, and Cocoon Nebulas. It blocks everything but the hydrogen-beta light these faint nebulas emit, providing the contrast needed for viewing. By isolating the hydrogen-beta spectral line centered at 486.1 nm in a 12nm band-pass and blocking other wavelengths, it effectively blackens the background sky, allowing the faint nebula to become clearly defined. It increases contrast even under dark skies so you can visually ...Read MoreDetails on Orion Hydrogen-Beta Nebula Filter, 1.25"

Orion Mars Observation Filter, 1.25"The custom-designed Mars Observation filter enhances contrast of virtually all surface features. Dielectric coatings transmit violet/blue ( 615nm) wavelengths where detail is rich, while blocking overbearing yellow/green (515nm-615nm) wavelengths. Polar icecaps appear more sharply defined, and differences in landscape shading are nicely resolved. Polar hazes and cloud cover become visible. The filter's high transmission makes it effective even in small telescopes. Custom-engineered filter comes with protective ...Read MoreDetails on Orion Mars Observation Filter, 1.25"

Orion Extra-Narrowband Tri-color CCD Imaging Filter SetImaging with extra-narrowband filters is the latest technique used by amateur astronomers for producing striking, high-contrast color CCD astroimages of emission nebulas. And it works even in heavily light polluted or moonlit skies. What you need is this three-filter set, which consists of Orion Hydrogen-alpha (#5587), Oxygen-III (#5578), and Sulfur-II (#5579) extra-narrowband imaging filters (1.25"). These specialized "line" filters transmit only the specific wavelengths of light important in emission ...Read MoreDetails on Orion Extra-Narrowband Tri-color CCD Imaging Filter Set
